Non-Extensive Approach to Quark Matter

TL;DR

This paper reviews non-extensive statistical methods applied to quark matter, exploring their thermodynamics and predicting hadron spectra in heavy ion collisions using a generalized Boltzmann approach.

Contribution

It introduces a non-extensive framework for quark matter based on composition rules and applies it to calculate hadron spectra from relativistic heavy ion collisions.

Findings

Non-extensive distributions can model quark matter thermodynamics.

Hadron spectra from heavy ion collisions are consistent with the non-extensive approach.

The generalized Boltzmann equation effectively describes subsystem energy composition.

Abstract

We review the idea of generating non-extensive stationary distributions based on abstract composition rules for the subsystem energies, in particular the relativistic generalized Boltzmann equation method. The thermodynamical behavior of such systems is investigated and hadron spectra stemming from relativistic heavy ion collisions are calculated by assuming quark coalescence.
